Safety precautions/instructions

Before commencing work, ensure that all sources of ignition have been removed.

Before commencing with any repair work on the gas tank, it must be completely emptied as per the legal requirements.
Before commencing any work on the lines of the gas system, all gas shutoff valves must be closed and the system emptied as per the legal requirements.
No open flames or smoking in the work area.
Avoid the formation of sparks (use spark-inhibiting tools).
Keep all combustible materials and objects away from fuel-burning devices.
Do not use any flammable substances to lubricate threads and valves of the gas system (oils, grease, etc.).
Wear protective clothing, safety gloves and safety glasses.
Keep suitable fire extinguishing devices at hand.
Perform a fire check of the hazard areas and surroundings after work has been carried out.
Never perform work in closed rooms.
All work involving assembly, disassembly and leak tests may only be performed by trained and authorized personnel
Workshop personnel must demonstrate their knowledge in accordance with the OSHA requirements (Occupational Safety and Health Administration) and be able to act accordingly.
All work involving assembly, disassembly and leak tests must be performed as per the relevant regulations and requirements of the ANSI, NFPA and UL standards (e.g. UL No. 1075 and NFPA No. 58).

Due to the fact that explosions can occur when the gas system leaks, a leak test must be performed before restarting the system after repairs have been done in which the pipes and lines of the gas system have been opened.

First aid measures:

Remove the affected person from the hazard area.
If eyes are affected, rinse them immediately and thoroughly (making sure that eyelids are open) with plenty of water.
If inhaled, and if drowsiness, headaches, visual impairment or irritation of the eyes, nose and throat occur, take the person into the fresh air. If the person is unconscious, place in the recovery position and check breathing and pulse. If there is no breathing or insufficient breathing, the preferable action is to perform mouth-to-mouth resuscitation. If necessary, carry out CPR.
Following skin contact, soak with water in the event of local frostbite injuries. The person should rest and be kept warm.

If any of these symptoms occur, consult a physician immediately.
